RESILIENT WHEEL.

- Specification of Letters Patent.

Patented sept. 7, 1915.

' Application med March 21, 1913.' serial No. 71555861, Y y

To all whom it may concern l Be it knownthat I, Dnvn) 'PnDDnN, 'acitizen of the United States, residing at Chicago, in the county of Cookand State of Figure lis a yvertical section through-'my' wheel in theplane of the axle; Fig. 2 isa section alongline .Q -210i? Fig. l; andFig. 3 is a sectionalong line 'B4-v3 of Fig. l'. Like parts areindicated by the same letters throughout the severalligures.

- The nat plate or disk Al is connected bymeans of the yoke members A1,A1 to thev hollow or tubular aXle A2. They cylindrical lug'A3 projectsoutwardly from the center of,

the'y disk A and terminates in a screwthreaded memberA A disk A5 ofsubstantially the same diameter as the disk A is mounted on thescrew-threadedvmember A4, being lheld snugly against the end 'of the lugA3 by the nut A6; lSpacing sleeves A7, A7k

are interposed between the disks A, A5 and n capl screws A8 providedwith tightening nuts A9 are adapted to tie the diskstogether,

these screws beingloc'ated within the spac ing sleeves A?. A pin A A10projects outwardly from the disk A at a point immediately below the lugA3 and may be if desired made integral with the disk A or otherwiseas-fthe case `may be. v projects inwardly from the yplate A5 'and isadapted to rclosely t and engage the end of the pin A1". The screw A12projects outwardly from the kend of the pin A10 through a plate A5 andis provided with a nut A13 whereby the disk may be firmly held againstthe end of the pin.- The ytwo disks are by the members above shown thusrigidly bound into position with respect one to the other in such wisethat they will maintain their parallelism and in such wise that thedistance between 'them will not vary andthat they are held againstrelative rotationaly displacement. f

The' annular ring, B1 isfv provided l,with ball'V bearings B1, B? inengagement respectively with the lat'inner'surfaces "of thedisks A,

A5, these bearings beingas vindicated, Fig.. 3 substantially continuousto give twoannular ball bearing/ringsof contactl between theannularring` B and they plates AA5 'respectively, thus leaving the annular ringB tree to rotate between` theplates and i'reeI to -move slidably in alplaney perpendiculary to its rotational axisl but held against rocksing movement. The pockets B3 Aare* locatedy i about the outer peripheryof'thering B, and in these pocketsareheldfthe spoke members B4, theouter endsv of which are engaged byy the pockets B5" on the 'tread' rimB6, which tread rim holds the Aspokes firmly imposition and isprovidedwith va'moreorless resilient cushion treadB7. The rings B6 and B, all

the spokesl and kindred parts thus form rotatable tread member or' wheelrotating between the Xed guide flanges or plates. v

A pneumatic tire C is'located on the in'- side of the annular ring B,being held in position therein by any suitable means. For instance, Ihave shown the bead of the tire kwhichin this' case Vis on thefoutsideinstead of on the inside engaged on one side by an inclinedsurface orchannel' wall C1 integral with and' forming a rigid part of the annularring B `and" on the other side by a wall C2 mounted on the ringy C3,which forms a The pin A10 has rotatably mounted there-7^ on a concaveroller or bearing wheel C5 supported on the ball bearings C6. Thisroller is adapted to ride upon the inner tread surface of the tire C.Thus, when the wheel supports the vehicle, the pressure or weight of thevehicle is applied through the axle A2 to the disks A,y A5` and sincetheV roller C5 is swung between thedisks A5 the weight of the car willbecentered within `the roller upon the tread surface of the pneumatictire, which tire is supported by the rotary tread member or wheel. y

"Ihe annular ring B is provided withy an inwardly vextending annularliange or collar D provided with gear teethras indicated at D1. Theplate A is apertured as at D2, and a driving pinionD3 rotatably mountedon the bearing DL on the plate Al is in mesh with the teeth D1. Thisdriving pinion is driven from the driving axle D5 through a miter gearD6 and miter pinion D?. When the driving aXle D5 is rotated by theengine in any suitable manner it causes the pinion D3 to rotate. Therotation of this pinion being as it is in mesh with the teeth onthetread member causes this member to rotate with respect to the fixedguide disks or plates and the car'will be driven forward. If this wheelwere to be used as an idler or front wheel instead of a rear drivingwheel it would be necessary to dispense with the driving pinion anddriving connections and to omit the gear teeth on the annular ring.

It will be evident that the wheel spokes are very short and thereforevery strong and not at all likely to break, bend or buckle. It will benoted that the turning or tipping moment such as is always present inthe automobile wheel is resisted by the annular ball bearings at pointsconsiderably removed from the center of rotation. Thus-the pressure uponthese bearings will at all times be very slight. f

The pneumatic tire is located within the wheel and protected from thedanger of cutting, puncturing and the like. It is in contact only withthe smooth bearing roller, and thus abrasion on the part of the tirewill be reduced to a minimum. As the tire expands and contracts underthe varying loads caused by the wheels going over bumps and intogulliesand ditches and the like or other irregularities in the road, thewheel will slide at a point between the guide plates but still continueto rotate, and, since the gear teeth on the driving pinion areapproximately radial, they will at all times be in mesh with the teethon the wheel and the wheel will at all times continue to be driven fromthe engine.

It will be evident that the drawing of my device is to a large extentdiagrammatic, but the device 1 have shown is operative, that is to sayit might be made to operate, although, of course, it is probable that inorder to make it a kcommercially successful device changes might have tobe made. I v wish, therefore, that my device be regarded` as in a sensediagrammatic and that it be understood `that changes might be made insize, shape and the substantial arrangement of parts without departingmaterially from the spirit of my invention.

1 claim l. A wheel having an inner and an outer tread and laterallyprojecting annular por-L tions intermediate the treads and a guidecomprising two disk-like parts of less diameter than'the wheel andrigidly secured together, the wheel being placed between them and heldin parallelism through the annular projections.

2. A wheel having an outer tread and inner pneumatic tread and twolaterally projecting annular portions, the guide consisting of twodisk-like bodies between which the wheel is inclosed, cross bars forconnecting them together, means for centering the wheel within the guideso that it projects therefrom and bearings between the annularprojections and the disks.

3. A wheel having an outer tread and inner pneumatic tread and twolaterally projecting annular portions, the guide consisting of twodisk-like bodies between Which the wheel is inclosed, cross bars forconnecting them together, means for centering the wheel within the guideso that it projects therefrom and bearings between the annularprojections and the disks, and means for rotating the tire.

4. A wheel comprising a rotary annular tread member, a pneumatic tire onthe inner side thereof, and a bearing roller in contact with andsupported by and free to travel along said pneumatic tire.
